When did individual writers begin to use word processors? As I began work on a literary history of word processing, I found it difficult to establish a time line. Sometimes writers kept a sales record—a word processor or computer would have represented a significant investment, especially back in the day. Other times, as with Stanley Elkin or Isaac Asimov, the arrival of the computer was of such seismic importance as to justify its own literary retellings. But most of the time there were no real records documenting exactly when a writer had gotten his or her first computer, and so I had to rely on anecdote, detective work, and circumstantial evidence.

Naturally I scoured The Paris Review’s interviews for mentions of writers and their machines. In addition to temporal markers, they sometimes offered rich insight about their views of the technology in relation to the creative process. Take Ian McEwan’s comments from his Art of Fiction interview:

In the mideighties I was a grateful convert to computers. Word processing is more intimate, more like thinking itself … I like the provisional nature of unprinted material held in the computer’s memory—like an unspoken thought. I like the way sentences or passages can be endlessly reworked, and the way this faithful machine remembers all your little jottings and messages to yourself. Until, of course, it sulks and crashes.

The computer is humanized, brought into the space of jottings and mumblings or musings, mood swings and household accidents.

Pictures proved to be as rich a method as any for reconstructing this history. I found myself squinting over images of writers posed alongside of their computers, running Google image searches, trying to match makes and models. There was also the way in which the computer gradually worked its way into the stock of collective imagery around writing and literature, something fully realized by the time R. Crumb drew Charles Bukowski “leering” into his Macintosh, for example. And then, of course, there were the advertisements, the magazine covers, the product manuals: a visual stockpile, an appealingly tactile record of this seemingly ephemeral topic. For many writers, after all, a word processor was as much an appliance as it was a deeply individualized instrument—more fax machine than fountain pen, as I say in the book. Still, the plastic, glass, and silicon devices had stories to tell, just as did the people pictured with them.

The story of word processing begins in the office. Like the typewriter before it, the word processor was a profoundly gendered technology. And remember that word processing originally meant something much more expansive than it does today. It once encompassed the complete flow of written information through an office environment: its production, reproduction, distribution, and filing. Dictation was as much a part of word processing as typing and transcription, and this is reflected in early product catalogs from IBM and other companies. Pictured above is a female operator in front of the IBM Magnetic Tape Selectric Typewriter (MT/ST), the product which IBM marketed as the centerpiece of its word processing line after it was rolled out in 1964. The operator typed at a Selectric; mistakes were corrected on the page, leaving behind the usual blemishes, but the correct character sequence was stored to the magnetic tape reels visible in the photograph. For the first time, the material act of composition and inscription was sundered, yielding a state in which the text, suspended on tape, could be revised indefinitely before producing final, “letter-perfect” copy with the touch of a button.

The first application of the MT/ST in a literary setting was by the British spymaster Len Deighton’s assistant, Ellenor Handley, who used one in Deighton’s high-tech home office to prepare the manuscript for his 1970 World War II novel, Bomber, (long-listed for the Man Booker Prize). The tape reels containing (as Deighton was to put it in his afterword) “the first book to be entirely recorded on magnetic tape” are long gone, but the final manuscript survives, now in the hands of a private collector; in 2013 Handley was reunited with it, revealing, if you look closely, the bite marks along the edges of the pages where the MT/ST’s mechanical tractor feed had once gripped: the enduring mark of the mechanism.

A decade later, word processors had taken the form we recognize today: a typewriter attached to a TV set. The creation of a working “TV typewriter” was a rite of passage for Silicon Valley hackers, including Steve Wozniak, who demoed one at the Homebrew Computer Club before he brought along the computer he called an Apple. By 1979, when he wrote a feature story for onComputing magazine, Jerry Pournelle was already an early adopter and proselytizer, having assembled a custom system built around a Zilog Z-80 chip, a sixty-four-character Hitachi monitor, and the CP/M operating system. He called it Zeke, short for Ezekial [sic]. Pournelle, like many early adopters, was a genre writer: the computer freed him from the labor of retyping, allowing him to spend more time revising his prose as well as dramatically increasing his output. “Boy, has this thing made it easier to write science fiction,” he told his readers. A couple of years later he entered into an amiable disputation with fellow sci-fi author Barry B. Longyear in the pages of Asimov’s magazine. The accompanying pen and ink illustration, by Jack Gaughan, captured much of the anxiety around early word processing, depicting the authors swallowed up by their machines to become both input and output in a never-ending loop.

Meanwhile, gag pieces advertising pencils or fountain pens as feature-laden “word processors” became a staple of the 1980s computer press. Peter McWilliams stretched the joke to a short book about the fictitious McWilliams II Word Processor (Portable! User friendly! Prints characters from every known language!). Users of all stripes were coming to grips with the strange new ontology of writing on the screen. “Writing with light” was the phrase authors invoked over and over again. “It seemed like the future,” Peter Straub said of his own IBM Displaywriter, bought to collaborate long-distance on The Talisman with Stephen King, who had at the time what he delighted in referring to as his “great big Wang.” But writing with light had its perils, too: notoriously temperamental floppy disks were given to spawning “bad sectors,” a phenomenon so rampant that Amy Tan founded a Kaypro computer-support group with that name shortly before the start of her own fiction career in San Francisco. Other writers worried what would happen when their words slid off of the edge of the glowing glass screen—the manual accompanying Perfect Writer, the Kaypro’s default software, came with a fanciful visual aid to illustrate the principle behind the scrolling mechanism, the better to reassure anxious users.

But computers were never just about screens and keyboards. They were also about writers, who had bodies. Sometimes this manifested itself in prosaic ways: a photo captures Eve Kosofsky Sedgwick, at work on the manuscript that would become Between Men (1985), reclining in a chair, the detachable keyboard of an Osborne 1 on her lap, a blanket underneath, her cat watching from above, as her head turns to look into the diminutive five-inch screen, a box of floppy diskettes visible alongside. As so-called portables (“luggables”) like the Osborne and Kaypro came on the market, they changed the array of available postures for writing with a computer—harbingers of the laptops and tablets to come.
